How long can a bottle of milk last without spoiling?

Factual Questions

In addition to how the milk is pasteurized, and whether you touch the opening, and whether you leave or on the counter, it depends on how cold your fridge is. Mine is barely above freezing (sometimes slightly below freezing) and I’m constantly surprised at how long our milk keeps.

Also, the ultra pasteurized stuff keeps a lot longer after opening it than the regular milk does, presumably because we don’t generally contaminate either, and the UP milk starts with less stuff that can grow.

Yep, old milk makes biscuits or the sweet cornbread the kids love so much.

Around here we’re more apt to be out of milk than have “old” milk, tho’.

Buttermilk will last months if kept cold. It’s a dangerous thing if left out. Explosive buttermilk is not pleasant. You gotta know you were bringing it up to your face at opening, to smell(why? It’s buttermilk, not a good odor, but it’s ingrained, open the carton and smell). Makes your skin so soft, tho’:blush:
